Logging a refuel
Choose fuel type
Select the fuel type (
tipoCombustible) that matches what you put in the tank. See supported fuel types below.Enter the amount spent
Type the total money spent on this refuel in the Amount spent field (
cantidadGastada). This is the only required cost field.Enter gallons and price per gallon (optional)
If you want efficiency calculations, fill in Gallons (
galones) and Price per gallon (precioPorGalon). KilomeTracker uses gallons to compute km/gallon and km/liter metrics.Add notes (optional)
Use the Additional notes field (
notasAdicionales) for any extra context — station name, location, or octane grade.Supported fuel types
Regular
Regular
Standard unleaded gasoline. The most common option for everyday passenger vehicles. Suitable for engines that do not require premium octane.
Premium
Premium
Diesel
Diesel
For diesel-engine vehicles including trucks, SUVs, and some passenger cars. Diesel records are included in cost and efficiency aggregations alongside gasoline records.
Eléctrico
Eléctrico
For electric vehicles. Use
cantidadGastada to record the cost of a charging session. Gallons and price-per-gallon fields can be left blank.Híbrido
Híbrido
For hybrid vehicles that accept both fuel and electric charging. You can log both fuel fills and charging sessions as separate records under this type.
V-Power
V-Power
Shell V-Power and equivalent premium performance fuels. Tracked separately from Regular and Premium for vehicles where you alternate between fuel grades.
Fuel analysis dashboard
The fuel analysis dashboard at/fuel-analysis/[alias] gives you a full picture of consumption and spending for a single vehicle.
Summary metrics
| Metric | Description |
|---|---|
| Total refuels | Number of refuel records logged for the vehicle. |
| Total spent | Sum of all cantidadGastada values. |
| Total gallons | Sum of all galones values across records that include gallons. |
| Average price per gallon | totalGastado ÷ totalGalones across all records with gallon data. |
Breakdown by fuel type
The dashboard groups records bytipoCombustible and shows, for each type:
- Count (
cantidad) — number of refuels for that fuel type - Total spent (
gasto) — cumulative cost - Total gallons (
galones) — cumulative volume
Charts
- Bar chart: cost by fuel type — compare spending across Regular, Premium, Diesel, and other types at a glance.
- Line chart: efficiency over time — see how your km/gallon trend changes across refuel dates.
Fuel efficiency metrics
Efficiency is calculated using the combined totals of gallons and distance from your route records for the same vehicle and time period.| Metric | Formula |
|---|---|
| km/liter | totalDistancia ÷ (totalGalones × 3.785) |
| km/gallon | totalDistancia ÷ totalGalones |
| cost/km | totalGastoCombustible ÷ totalDistancia |
Efficiency metrics require at least one refuel record with a
galones value and at least one route record for the same vehicle. Records without gallons contribute to cost totals but not to efficiency calculations.Filtering by date range
On the fuel efficiency endpoint, you can passstartDate and endDate (format YYYY-MM-DD) to scope the calculation to a specific period. This lets you compare efficiency across different seasons, drivers, or driving patterns.
On the Refuels History page, you can filter records by vehicleAlias, tipoCombustible, startDate, and endDate.
Deleting a refuel
To delete a refuel, open Refuels History, find the record, and click the delete icon. Confirm the action in the dialog.Related pages
